Brief Product Description

The Bently Nevada 330703-000-080-10-02-00 is a high-precision 8mm proximity probe designed for non-contacting vibration and displacement measurements in turbomachinery. This sensor provides critical data for condition monitoring systems, ensuring the mechanical integrity of rotating assets in demanding industrial environments.

​Product Description

The Bently Nevada 330703-000-080-10-02-00 serves as a vital sensing component within the 3300 XL 8mm Proximity Transducer System. This eddy current sensor measures the thin film of oil or the distance between the probe tip and the observed conductive target, typically a rotating shaft. By converting this physical displacement into a proportional voltage signal, the probe enables the monitoring of axial position, radial vibration, and rotational speed. These measurements allow operators to detect early signs of bearing wear, shaft misalignment, or rotor instability before catastrophic failures occur.

Precision Engineering for Severe Environments

Bently Nevada manufactures this probe using high-grade stainless steel and specialized polyphenylene sulfide (PPS) tip materials to withstand extreme industrial stressors. The probe tip remains impervious to common lubricants, moisture, and chemical exposure, while the robust cable assembly prevents signal attenuation. Furthermore, the 3300 XL series features improved resistance to electromagnetic interference, which ensures data signal purity even when routed near high-voltage machinery. The probe’s physical design facilitates easy gapping and installation into tight internal bearing housings or external brackets.

Standardized Quality and System Integration

This proximity sensor integrates seamlessly with 3300 XL Proximitor Sensors and extension cables to form a complete calibrated system. Because the 330703-000-080-10-02-00 complies with stringent ISO quality standards, it delivers a linear output over a wide temperature range, significantly reducing the need for frequent recalibration. The IP67-rated enclosure protects the internal sensing elements against dust and temporary immersion, making it a reliable solution for outdoor turbines, pumps, and compressors. By providing stable, high-frequency response data, this sensor enhances the effectiveness of Turbine System Instrumentation (TSI) and predictive maintenance programs.
